   I don’t like hunting around for service stations with free, working air pumps to keep my tires at proper inflation…so I decided to invest in a portable compressor. I wanted one that had a built-in gauge to avoid having to switch back to a separate gauge. The TyphoonMax 300 fit the bill. However, the chuck threads onto the tire stem, rather than quick-fastening. This results in a loss of anywhere from 2-4 pounds of pressure when you remove the chuck, no matter how quickly you unscrew it. You then have to doublecheck your pressure with a separate gauge once you’ve removed the Typhoonmax chuck. This defeats the purpose of a built-in gauge! This device may be appropriate for vehicles with really large tires, but if you only are trying to maintain proper inflation of standard car tires, there is no need for a screw-on chuck that you can leave for a few minutes.
   Also – another annoyance – the power and chuck cables come shipped neatly stored in the back of the device, but the power cord is impossible to “re-store” in the same position, forcing you to leave it hanging or wrapped around the device when not in use.

   The unit does have an on-offswitch, inflates fairly rapidly, and is not too noisy. But the product design oversights above are making me consider returning it and purchasing a more convenient alternative.

   I’ve been delighted with this item since I got it, especially since I have a tire that for years slowly deflates [it’s not the tire, probably a slightly warped wheel). I tried another plug in model, and it took about half an hour to inflate one tire: that was a joke. This thing works as planned. I plug it into the lighter socket (leave the motor running so you don’t drain the battery) and this unit easily reaches each tire (through an open window) and gives you a read out. I know others have complained about losing 1 or 2 psi while unscrewing the chuck. Well, it’s a high quality brass chuck, and I’m supposing there’s a reason you don’t have a cheapo clip on a tire that has the weight of a car or truck on it. So I fill to 2 psi above the recommended, and then unscrew. I don’t bother remeasuring.

   This unit is quick, so in a minute or so I’ve brought my tire up to pressure, and it’s easily portable to the next tire. I’m very happy with my purchase.

   This unit is well designed, easy to use. I like this unit’s screw-on fitting better than the clamp-on type that most pumps come with. You lose a tiny bit of air – less than 1 psi – while screwing it on or off. But it stays on more securely than the clamp-on kind. The guage is great – even though it reads all the way up to 250 psi, it has an expanded scale down around 30 psi where car tires like to be, so you can tell the difference between 29 and 30.
